पाकिस्तान को कच्चा चबगयेगी ये भारतीय किलर शार्क,Kalvari has a superior stealth technology compared to previous diesel-electric submarines. She can also launch massive attacks through precision guided weapons. An attack can be launched through this submarine with torpedoes as well as tube launched anti-ship missiles on the surface of the water or beneath it as well. She can work in all settings including the tropics, wherein various means and communications are in place to ensure interoperability with various components of the naval task force. Numerous defence activities can be carried out through this stealth submarine including mine laying, area surveillance, anti-submarine warfare, intelligence gathering and multifarious warfare activities. Kalvari is being constructed from special steel and she can withstand high yield stress because she possesses tensile strength, moreover she can withstand hydrostatic force of high magnitude and dive deeper into the oceans.

These attack submarines are also equipped with diesel propulsion and extra air independent propulsion. The new diesel electronic Scorpene submarines will be named as per the old Foxtrot-class submarines decommissioned around 10 years ago; these were the first submarines of the Navy. INS Kalvari is one of a set of six submarines which will undergo test and trials for one and a half years rigorously at harbour and on sea whether on the surface or underwater. Mechanisms on this submarine have been designed to optimize safety; DRDO is in the process of establishing a system for carrying out structured health monitoring of under development nuclear submarines as well as future conventional Naval submarines.[10]
